James A. Blackburn, Jeffrey E. Marchese, Matteo Cirillo, Niels Grønbech-Jensen

摘要:

用经典的RSCJ模型分析了由两个电容耦合电感回路组成的电路,每个回路被一个约瑟夫森结中断。同样的电路最近进行了实验研究,其结果被用来证明在系统中的量子力学纠缠,通过观察初始微波扰动后的两个感应回路的相关状态。我们的经典分析表明,所观察到的现象完全存在于经典的RSCJ模型,我们提供了一个详细的直观描述的瞬态动力学负责的意见。

英文摘要:

An electrical circuit consisting of two capacitively coupled inductive loops, each interrupted by a Josephson junction, is analyzed through the classical RSCJ model. The same circuit has recently been studied experimentally and the results were used to demonstrate quantum mechanical entanglement in the system by observing the correlated states of the two inductive loops after initial microwave perturbations. Our classical analysis shows that the observed phenomenon exists entirely within the classical RSCJ model, and we provide a detailed intuitive description of the transient dynamics responsible for the observations.
